“Have you hunted goats?” the boys demanded.

“What I’ve not hunted, ain’t,” said the man. “I don’t know what folks want goats for, though. They’re the hardest work to get, and no good when you get ’em. A bighorn, now!”

“What’s a bighorn?” asked Joe.

The man looked at him in profound surprise. “By glory, don’t you know what a bighorn is?” he demanded. “Where do you come from, anyhow? A bighorn’s a Rocky Mountain sheep, the old ram of the flock, with horns fifty inches long that curl around in a circle, and he’s the handsomest, finest, proudest lookin’ critter God Almighty ever made. Wait till you see one!”

“Do you think we can see one in the Park this summer?” the boys asked.

“If you climb up a cliff about seven thousand feet and make a noise like a bunch o’ grass, I reckon maybe you can,” said the stranger.

The next three hours were about the longest the boys had ever spent. They went back into the sleeper as soon as the berths were moved out of the way and they could sit at the window, and with their faces glued to the pane strained their eyes ahead to see the mountains. Whenever the road made a curve, they could see them plainly, a vast, sawtooth range of blue peaks, some of them sharp like pyramids, some of them rounded into domes, marching down out of the north and stretching away to the south as far as the eye could see. Not only were they bigger mountains than the scouts had ever seen, even on a trip the year before to the White Mountains in New Hampshire, but all over them, on their summits, in great patches on their sides, sometimes quite covering an entire peak, were great fields of snow. Here it was about the 4th of July, with flowers blooming in the grass beside the track and a blazing hot sun in the heavens—and the mountains just out there covered with vast fields of snow!

“Gee, I wish the old engineer’d put on some steam!” sighed Joe.

“I wish he would,” Tom answered. “But I guess that snow ain’t all going to melt before we get there. Say, Joe, why do you suppose that range goes right up out of the prairie without any foot-hills? Remember, when we went to the White Mountains we got into smaller mountains long before we reached Washington? They went up like steps. But here the Rockies just jump right up out of the plain.”

“I don’t know—wish I’d studied geology. Maybe the guy who had the friend who walked with the Englishman can tell us.”
